本文分析了双脉冲运转的种子注入激光器及其存在的问题，在此基础上首次提出了用相位共轭主振荡器功率放大（MOPA）激光器组成高重复率n脉冲运转激光器系统的新方法，获得了重复率可达几千Hz且高相干度的脉冲输出，该系统具有相当好的性能，可望替代种子注入激光器而成为动态全息检测领域的一种新光源．
In this paper, we analyzed the double-pulse seed injection laser and its existing problems. Based on this, we proposed a new method to form a high repetition rate n-pulse laser system using phase-conjugate main oscillator power amplifier (MOPA) A pulse output with a repetition rate up to several thousands of Hz and high coherence is demonstrated. This system has good performance and is expected to become a new light source in the field of dynamic holography instead of a seed injection laser.
